Needed sound fx and voiceover Animation programs?

Firstly I do not want a complicated or high end professional stop motion program. I also do not want to spend more than say $80 dollars. I want it to have sound capability such as sound fx and voiceover. I do not want to have to export to another program to add sounds. It is for windows use by the way not mac.I will be using it with a Logitech Pro 9000 webcam.

All your suggestion helps me to take decision !!
